E)is document addresses design items to be aware of when migrating working designs among Fury-, DustDevil-, Tempest-, and Firestorm-StellarisВ® microcontrollers (MCUs) and Tivaв„ў C Series TM4C123x-class MCUs. Topics covered include both software and hardware issues as well as feature changes and enhancements. All software issues are comprehended in the Driver Library APIs. As a result, syste

Скачать »Application Notes, PDF, 172 Кб, Rev. C, 06-11-2013Configuring StellarisВ® Tempest- and Firestorm-Class and MCUs W/ Pin Multiplexing (Rev. C)Many members of the StellarisВ® family of microcontrollers provide system designers with a great deal of control over the placement and selection of peripheral module signals that are alternate functions for GPIO signals. This application note provides an overview of the pin muxing implementation, an explanation of how a system designer defines a pin configuration, and examples of the pin confi

Скачать »Application Notes, PDF, 301 Кб, 07-07-2009Using a 9-bit Software UART with Stellaris (AN01280)This application note describes how to extend the functionality of the standard hardware UART available on StellarisВ® microcontrollers by using the 9-bit UART add-on.

Скачать »Application Notes, PDF, 127 Кб, Rev. C, 01-11-2012StellarisВ® LM3S ADC Calibration (AN01282) (Rev. C)This application report describes a method for improving the absolute accuracy of the analog-to-digital converters (ADCs) found on StellarisВ® LM3S microcontrollers. Due to inherent gain and offset errors, the absolute accuracy of the ADC is affected. The methods described in this application report can improve the absolute accuracy of the ADC results.

Скачать »Application Notes, PDF, 95 Кб, Rev. A, 08-01-2013ADC Oversampling Techniques for Stellaris Microcontrollers (AN01239) (Rev. A)Some members of the Stellaris microcontroller family have an analog-to-digital converter (ADC) module. The hardware resolution of the ADC is 10 bits; however, due to noise and other accuracy diminishing factors, the true accuracy is less than 10 bits. This application report provides a software-based oversampling technique, resulting in an improved effective number of bits (ENOB) in the conversion
